---

一．配置nginx

systemctl stop firewalld.service

systemctl disable firewalld.service

setenforce 0

安装依赖环境

yum install -y pcre-devel zlib-devel openssl-devel gcc gcc-c++ make

创建运行用户、组

useradd -M -s /sbin/nologin nginx

上传nginx-1.15.9.tar.gz至/opt目录

cd /opt

tar xzvf nginx-1.15.9.tar.gz    解包

cd nginx-1.15.9/    准备编译

./configure \

--prefix=/usr/local/nginx \

--user=nginx \

--group=nginx \

--with-http_stub_status_module

make j3 && make install    安装

路径优化

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/

添加 Nginx 系统服务

vim /lib/systemd/system/nginx.service

[Unit]

Description=nginx

After=network.target

[Service]

Type=forking

PIDFile=/usr/local/nginx/logs/nginx.pid

ExecStart=/usr/local/nginx/sbin/nginx

ExecReload=/usr/bin/kill -s HUP $MAINPID

ExecStop=/usr/bin/kill -s QUIT $MAINPID

PrivateTmp=true

[Install]

WantedBy=multi-user.target

chmod 754 /lib/systemd/system/nginx.service    给权限

systemctl enable nginx.service    开机启动

systemctl start nginx.service   启动nginx

nginx -t  检查nginx配置文件

二．部署两台tomcat

systemctl stop firewalld

systemctl disable firewalld

setenforce 0

上传所需要的安装包到  /opt

pache-tomcat-9.0.16.tar.gz    jdk-8u201-linux-x64.rpm

解压：

查看java版本     java -version

rpm -ivh jdk-8u201-linux-x64.rpm   解jdk包

设置JDK的环境变量

vim /etc/profile.d/java.sh                          #/etc/profile.d/  环境变量脚本目录   

export JAVA_HOME=/usr/java/jdk1.8.0_201-amd64    #输出指定java所需的类文件

export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar #可执行文件的位置

export PATH=$JAVA_HOME/bin:$PATH

source /etc/profile.d/java.sh  全局变量加载生效

java -version   再次查看版本会有所变化

cd /opt

tar zxvf apache-tomcat-9.0.16.tar.gz  解包

mv apache-tomcat-9.0.16 /usr/local/tomcat    #将解压后的包剪切到/usr/local 目录中，并改名为tomcat

ls /usr/local/tomcat  查看

优化管理tomcat

ln -s /usr/local/tomcat/bin/startup.sh /usr/local/bin/

ln -s /usr/local/tomcat/bin/shutdown.sh /usr/local/bin/

启动、关闭tomcat

startup.sh   开启

ps -aux | grep 8080    检查开启

shutdown.sh  关闭

优化Tomcat

vim /usr/java/jdk1.8.0_201-amd64/jre/lib/security/java.security

securerandom.source=file:/dev/urandom    修改117行

备份tomcat配置文件 cp

/usr/local/tomcat/conf/server.xml /usr/local/tomcat/conf/server.xml.bak

三.tomcat配置

1.tomcat1

mkdir /usr/local/tomcat/webapps/test

vim /usr/local/tomcat/webapps/test/index.jsp     #动态页面的配置

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<% out.println("动态页面 1,http://www.test1.com");%>

2、tomcat1 添加虚拟主机配置

vim /usr/local/tomcat/conf/server.xml

  

           #新增

shutdown.sh

startup.sh

3．tomcat2配置

tomcat2 添加虚拟主机配置

四、Nginx 配置负载均衡，反向代理

echo ‘

nginx

’> /usr/local/nginx/html/index.html

设置静态图片

配置负载均衡、反向代理

vim /usr/local/nginx/conf/nginx.conf

http {

......

 #gzip  on; 

   

    upstream tomcat {              

      server 192.168.226.129:8080 weight=1;

      server 192.168.226.132:8080 weight=1;

    }

 server {

        listen       80;

        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location ~ .*\.jsp$ {

            proxy_pass http://tomcatserver;   

           proxy_pass指令设置的主机名

            proxy_set_header HOST $host;

            proxy_set_header X-Real-IP $remote_addr;

            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

            }

location ~* \.(gif|jpg|swf|jpeg|bmp|ico)$ {    

           root /usr/local/nginx/html/img;

           expires   1d;

           }       

        location / {

            root html;

            index  index.html index.htm;

        }
